One of the easiest ways to add storage to your computer with simple plug-and-play operation. Ready to use with your PC and no software installation required. Intuitively drag and drop files to and from your laptop or PC.

Free up space on your internal hard drive by transferring files to your portable hard drive. With up to 4TB1 capacity, you can save your massive collection of photos, music, and videos without slowing down your PC.

If you are ready to get into the internals of hard drive you can do that how to convert a USB HDD drive board to SATA HDD drive and you will need to invest money into another board, and the tools + software required. Is it worth it ?

Connected a 4-Port Ultra-Slim USB 3.0 Hub to a Toshiba P755 series laptop (running Windows 10) with a single USB 3.0 port. For some reason when I try to connect a independently powered external USB 3.0 hard drive to the hub the external USB drive continuously connects/disconnects and ultimately never connects to PC.

I would contact @AnkerSupport via sup...@anker.com and give them your model/serial number, date of purchase, and list out what troubleshooting you have tried. They should give you more details on the hub is suppose to work and help resolve your issues with the hub.

Thanks for the suggestion. Have gone ahead and emailed Anker.com support. Hub appears to work fine with flash drives I have. Just has a problem with two different brands of powered USB 3.0 hard drives on two separate Toshiba P755 laptops.

The two USB 3.0 hard drives I tested have their own independent power supply. As such why would it be an issue of the hub not supplying enough power? One would think (and assume) that powered USB drives would be immune from the hub not being able to supply enough power. Not to mention the hub works perfectly fine with these two powered USB hard drives when connected to a USB 2.0 port on these two laptops.

I had a similar issue in the past with a different computer and hub. What worked for me was using a different cable than the one that came with my hard drive. But it could have been that or the fact that I had everything hooked up and restarted my computer, so it was connected when it booted up. Either one of those things fixed it for me

Tired different USB 3.0 cables to the powered USB 3.0 hard drives and even tried a USB 3.0 extension cable. Tried powering on the powered USB drives after booting the PC and before booting the PC. No joy.

My USB 3.0 1TB Toshiba External HDD works fine with my Windows desktop and my Xubuntu 16.04 LTS laptop. Both of them recognize and utilize the USB 3.0 feature of my hard drive. However my other laptop (now with Elementary OS Loki, which is based on Ubuntu 16.04 LTS) fails to recognize my external HDD when I plug it in a USB 3.0 port even though it works fine when I plug it to a USB 2.0 port.

I know that there are other threads similar to my problem but I'm quite confused because my external HDD works with my Xubuntu laptop but doesn't work with my current Elementary OS laptop (btw it also didn't work for this laptop when it was still running the same distro, but I think it worked when this was still running Fedora 24). I can't really say that my USB 3.0 port is broken because it works fine with my USB 3.0 flash drives. I'm thinking that maybe there are some packages that I need to install/remove to make it work.

I also have a Toshiba 1 TB external hard drive with USB 3.0 connection. When I plugged it into my Asus Zenbook UX305UA with elementary OS Loki running on battery, the hard drive was not recognized, neither on the USB 3.0 nor the USB 2.0 port (although it got powered up...). Only once I connected the laptop to power and then plugged in the hard drive, it popped up in the file manager.

2. The problem occurs via OMV and shared via SMB. But also when I connected the HDD to my Windows laptop directly via USB. So that rules out OMV or SMB issues. Unless OMV or SMB somehow corrupted the drive or filesystem.

3. I have a feeling it is file related. Because this "slow mode" usually seems to kick in when copying a lot of small files. A WordPress folder for example. I've copied 500GB worth of large video files at a consistent 85MB/s. But after it goes into this "slow mode", also large files don't go fast anymore. The same (large) file will write with a stable 85MB/s from start to finish when it's functioning properly. And in "slow mode" it stays at 0b/s with some jumps to the 200kB/s range. And for a short while (2 seconds) to 5MB/s.

4. Also I noticed in this "slow mode", when you start a file transfer, it starts with 100+MB/s for the first 2 seconds, and then radically drops down to 0. Like a buffer is filled quickly somewhere, but it can't empty the buffer to the drive fast enough.

5. Yesterday evening, I gave up. Anything I tried to copy slowed down to 0 within a couple seconds. I just left it like that for the night (connected, mounted, but idle). The next morning, it wrote half of a 1GB iso at full 85MB/s speed. And then slowed down again.

7. At some point, I could not get OMV to shutdown or restart anymore. It would hang at "Power Down Reached" or something similar. When I pulled the HDD from the USB port of the proxmox server and connected it to my windows laptop, I could not open the main folder. It said it was corrupted. After running chkdsk /f it found 2 errors and fixed it. And everything was accessible again.

I don't know what to try anymore. It can't be hardware, since getting a fluke 2 times in a row from separate stores is almost impossible. It's not OMV, since it's the same directly connected to the laptop.

You format the drive and start using it and everything seems fine. No speed difference to my older 2TB 2.5" CMR drive. But after filling it with a couple 100 gigs, it starts to slow down HARD to almost useless write speed (

I'll try to return it and get a CMR/PMR drive instead. Unfortunately they seem extinct in the 2.5" size class. Back in 2014, I randomly bought an External 2TB 2.5" HDD for 90EUR and it turned out to be CMR. Why did everyone stop making 2.5" 2TB PMR/CMR drives?

But is it normal to slow down so extremely much while writing large files? I've read about speed slowing down from 100+ to 10MB/s when the regular tracks are full and the drive is forced to write in shingled tracks. But nowhere do I see people getting almost 0 like I am.

Because such slow performance was already reported repeatedly for 2TB USB drives from various brands I'd suspect hardware to be the root cause. Either due to same USB-to-SATA controller or the drive itself.

I still can't believe this SMR type is being sold to the regular public just like that. And it's 90% of the 2TB 2.5" market as well. No warning, nothing. You REALLY have to look hard for a "normal" PMR type. Where is EU regulation when you need them...

Hmm,, even the read speed is slow now (drive 60% full). 15MB/s (large files). That should not be the case with SMR, should it? As far as I've been able to find out, read speed should be the same as with normal PMR/CMR drives.

Hi, simply as above. Tried both USB ports, switched TV to standby and back on whilst the Hard drive is plugged in and nothing. It just says no USB device connected. I thought I had confirmed (elsewhere) that this drive was compatible.

Thanks James. The cable solved the problem. The TV now recognises the hard drive and we can record (I'm not sure if it was a power problem or a cable problem as I have only plugged in the HD USB and it worked straight away, no need to plug the other USB in!). The problem we have now, which I have read is an issue, is that we can't record one channel and watch another and when the TV is on stand-by, it won't record either. I believe the solution is to update the TV's firmware. I will check the version we have and investigate how this is done. Thanks for your advice.
